Check the capacitors on the motherboard. Look for bulging tops or goo on the caps.
Agree with the 40/40/20 percentage. Look up P4 and bad caps.
PIII. capacitors are fine. |

I swear this case is a PITA to open. |

got the case opened. ok, there's a plug for a FAN next to the P1 connector on the mobo. This plugs into the PSU. The new PSU does NOT have this connector for the FAN. also, there appears to be a pin missing in the P1 connector on the new PSU, which the old PSU has. The mobo has a plug for the cpu fan, and one for the case fan.
what do I do?
edit: the FAN next to the P1 connector on the mobo says PS FAN. I'm assuming it's the Power Supply FAN.
edit 2: I'm guessing it's a "2-wire / 3-pin signal connector from power supply to motherboard, allowing users to monitor the power supply's fan via the motherboard's BIOS" |

If you want to give us specifics about the machine brand/model number and the brand model of the supply we can double check that everything is fine.
To answer your questions in the absence of such information:
It should be a fan speed monitoring connection. If your psu doesn't have one don't worry about it. It shouldn't hurt anything and your psu fan should spin regardless.
The lacking pin on the p1 is probably the -5 volt which is largely obsolete.
Again if you have any concerns about what you are connecting up give us brand and model numbers of the psu and the machine you are working on and we can check to make sure everything is ok and that I'm not misunderstanding something. |

thanks for the reply. Antec BP350 PSU. looking at the p1 connector with the clip on top, it's the 3rd from upper right that's missing. |

| You are looking at the 20 pin without the 4 pin that goes with it to make the 24 pin as in this:

That is the -5 that is missing. You shouldn't have any problems with a p3 atx motherboard. Just don't worry about connecting anything into the ps fan connector on the motherboard. |

Thanks. The PSU does have a 4 pin connector to make it a 24 pin one, which I won't be using. But that pic is exactly it. I can finally finish this. |
